Capacities For AUDI A6 (4F_) From My 2005

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2022 Audi SQ5, 2022 Audi Q5 e, 2022 Audi Q5, 2021 Audi SQ5, and 2021 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Also applies to the Audi S 6 and the Audi RS 6.

Features of the refrigerant system:

Vehicle model Production period Total quantity of oil in refrigerant circuit in cm(1) Quantity of refrigerant oil in replacement compressor in cm(1)
Audi A6/S 6 From 04/2004 130 + /- 10 130 + /- 10
Audi RS 6 From 05/2008 130 + /- 10 Depending on the version of the A/C compressor (see note below)
  • 130 + /- 10
(1) The compressor installed at the factory for a 10-cylinder TFSI engine (Audi R S6) has a smaller quantity of refrigerant oil (70± 10 cm ) than the compressor for the 10-cylinder FSI engine (Audi S 6) and other engines (130 ± 10 cm ) due to the different testing procedures for the engines (the compressors at present differ only in part number and quantity of refrigerant oil, see also the A/C compressor data plate). When adjusting the total oil quantity in the refrigerant circuit for a 10-cylinder TFSI engine (Audi RS 6) at the factory, the oil quantity that was reduced in the compressor (60 ± 10 cm ), has to be filled somewhere else in the refrigerant circuit. This is not necessary during servicing, since the replacement A/C compressor is delivered with the original oil fill capacity (130 ± 10 cm ) (it would only be necessary during servicing if a new A/C compressor with a lower oil capacity was being installed). Refer to the Parts Information.
NOTE:

The replacement compressor contains the full quantity of oil intended for the refrigerant circuit. On A/C compressor replacement, the quantity of oil in the A/C compressor is therefore to be adjusted.

The Audi A6 are equipped with different A/C compressors depending on engine and production period.

This A/C compressor is available as replacement parts with different versions therefore note the exact part number. Refer to the System Overview - Refrigerant Circuit and the Parts Information.

A data plate may be attached to the A/C compressor by the manufacturer, indicating the part number and refrigerant oil quantity.
